I have a problem with my models not showing up the textures correctly.
The top left image shows a test model with the messed up texture. The bottom left shows the model in blender as it should look. The right hand images shows another model I made, loaded in exactly the same way, but for some reason does not have the same problem. I’m not sure if it is a model export problem or opengl code bug.
If anyone has had a similar problem before and can suggest something, that would be great.
Looks like messed up UVs and a texture without proper overfill on the seam, but how should we judge without knowing what engine/framework you use (if any) and how the topology of the model on the left is 
Could you show a wireframe of the model?
It is still very possible that the model is messed up, did you (re)build the normals and check for hidden/double vertices/edges, did you triangulate correctly?
Thanks I tried " (re)build the normals and check for hidden/double vertices/edges"
and that seems to have sorted it.
